摘　　要：以沧豆13为试验材料,研究河北夏播大豆生长动态发展规律。结果表明,大豆的籽粒产量与生物学产量呈极显著的相关关系,相关系数为0.952,上段、中段、下段粒质量分别占全株粒质量的46.9%,34.0%,19.1%;干物质积累、生长速率和叶面积指数都呈现先增加后减少的变化趋势,大豆总干物质质量和叶面积指数在籽粒形成始期(R5)达到最大。Cangdou 13 was used as experimental material to study the growth dynamics of summer sowing soybean in Hebei. The results showed that there was a significant regression relationship between grain yield and biological yield of soybean, and the correlation coefficient was 0.952. The grain quality of the upper, middle and lower parts accounted for 46.9%, 34.0% and 19.1% of the grain quality of soybean, respectively. Dry matter accumulation, growth rate and leaf area index showed a trend of first increase and then decrease, and the total dry matter quality and leaf area index of soybean reached the maximum at the beginning of grain formation（R5）.
